Utility model content
Technical problem to be solved in the utility model is to provide when a kind of user of maintenance reads and writes from the distance of desktop, students in middle and primary schools' desk for preventing myopia capable of preventing myopia.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Students in middle and primary schools' desk for preventing myopia, comprise a pin, desktop, table bucket and Support for preventing myopia, described table pin is connected to the bottom of table bucket, the front side of described desktop and the front side of table bucket hinged, offering the groove for placing books at the rear side of desktop, being hinged with the cover plate with matching grooves at the rear side of groove; Described Support for preventing myopia comprises transverse slat connected vertically and riser, and described transverse slat is connected to the bottom of desktop interlude slidably by guide rail, described riser and vertical and stretch out on the table; Described table pin is extension table pin.During use, by the height of desk with adjustable pin, make the height that desk reaches suitable; When writing, tabletop level shape, slides out to appropriate length by Support for preventing myopia bottom desktop, make the distance that desktop distance user is suitable, when user's head is too low, head is held by the supporting plate on myopia-preventing frame, makes to maintain a certain distance between eyes and books; When user is when reading, desktop is adjusted to suitable gradient, cover plate is dug, books are placed in groove, then Support for preventing myopia is slided out to appropriate length bottom desktop, prevent user from even flutterring on the table to desktop is close, the distance of eyes and books can be kept, play pre-myopic-preventing object, and prevent the incorrect sitting-pose of user's hunchback etc., bookish light is better in addition.
In order to make the books of different length can be placed in groove, in described groove, adjustment rod member can being provided with, having the locating piece that can move up and down location regulating the bottom overcoat of rod member.
In order to regulate locating piece more easily, described adjustment rod member can comprise two adjusting rods be parallel to each other, and two inner sides regulated are provided with positioning tooth; Described locating piece both sides are provided with the sleeve pipe coordinated with adjusting rod, are provided with the climbing gear coordinated with positioning tooth in sleeve pipe, and two adjusting rods are enclosed within sleeve pipe respectively, and climbing gear and positioning tooth engage each other.
In order to meet the use of the students in middle and primary schools of differing heights, described riser can be Height Adjustable scalable riser.
Integrated man-machine analyzes, the height of students in middle and primary schools' desk gets the sitting height of male sex's (8-12 year) 95%, the width of students in middle and primary schools' desk gets the maximum shoulder breadth of male sex's (12-18 year) 95%, and the seat that the length of students in middle and primary schools' desk gets male sex's (12-18 year) 95% is dark.The height of described desktop can be 670-760mm, and the width of desktop can be 450-550mm, and the length of desktop can be 550-650mm.The best height for desktop is 720mm, and the width of desktop is 500mm, and the length of desktop is 600mm.
When reading, can be easier to make user books are adjusted to suitable angle and height, the front side distance of the front side distance desktop of described groove can be 200-300mm.
Compared with prior art, the incorrect sitting-pose that Support for preventing myopia on desk of the present utility model can prevent user from bowing when reading and writing and books are excessively near and hunchback etc. affects one's power of vision, and by regulating the distance of Support for preventing myopia and desktop, meet the demand of different users; In addition can the gradient of desktop adjustable, user can need to come adjusting angle according to itself, reaches oneself satisfied effect; Table pin can regulate height, carrys out the multiple self-demand of the user of satisfied different height, to reach more comfortable effect; The reading that groove on desktop can be used for user convenient, the angle simultaneously by regulating the angle of cover plate can regulate book and desktop.
